So the good news is your issue seems to be just a DNS configuration issue, not a Zimbra issue.

Perhaps just use the dnsmasq configurations I suggest in my other blog post -- adjusted for your environment of course! Get rid of BIND9 and whatever else you are trying to use, and just use dnsmasq?

Hope that helps,
Mark

Ok, I surrendered to dnsmaq.

I think my tests are now ok, but I can't access via browser. What exact URL should I use? I tried a few:
    mail.mateuscentos7.hopto.org;
    mail.mateuscentos7.hopto.org:8443;
    mateuscentos7.hopto.org:2601 (I redirected all access from 0.0.0.0/0 port 2601 to 10.1.1.43:8443);
    mail.mateuscentos7.hopto.org:2601.

Test 1:

Code: Select all

[root@mail zcs-8.8.8_GA_2009.RHEL7_64.20180322150747]# host mail.mateuscentos7.hopto.org
mail.mateuscentos7.hopto.org has address 10.1.1.43
[root@mail zcs-8.8.8_GA_2009.RHEL7_64.20180322150747]# host mail
mail.mateuscentos7.hopto.org has address 10.1.1.43

Test 2:

Code: Select all

[root@mail zcs-8.8.8_GA_2009.RHEL7_64.20180322150747]# host 10.1.1.43
43.1.1.10.in-addr.arpa domain name pointer mail.mateuscentos7.hopto.org.

Test 3:

Code: Select all

[root@mail zcs-8.8.8_GA_2009.RHEL7_64.20180322150747]# host www.yahoo.com
www.yahoo.com is an alias for atsv2-fp.wg1.b.yahoo.com.
atsv2-fp.wg1.b.yahoo.com has address 72.30.35.10
atsv2-fp.wg1.b.yahoo.com has address 72.30.35.9
atsv2-fp.wg1.b.yahoo.com has address 98.138.219.232
atsv2-fp.wg1.b.yahoo.com has address 98.138.219.231
atsv2-fp.wg1.b.yahoo.com has IPv6 address 2001:4998:58:1836::11
atsv2-fp.wg1.b.yahoo.com has IPv6 address 2001:4998:58:1836::10

Test 4:

Code: Select all

[root@mail zcs-8.8.8_GA_2009.RHEL7_64.20180322150747]# dig mateuscentos7.hopto.org mx
